A. If disk scrub is enabled， all BIOS settings for the server are erased.
B. If disk scrub is enabled， all the data access on any local drives is destroyed.
C. If disk scrub is enabled， the LSI active RAID is destroyed but data is still preserved.
D. If disk scrub is disabled， all data on any local drives is preserved， including the local storage configuration.
E. If disk scrub is enabled， all data on any local drives is preserved， including the local storage configuration.

A. Adjacency Server is required when OTV is deployed with unicast-only transport.
B. Adjacency Server is required when OTV is deployed with multicast-enabled transport.
C. Each OTV device wishing to join a specific OTV logical overlay needs to first register with the Adjacency Server.
D. Each OTV device trying to join a specific OTV logical overlay needs to be configured as an Adjacency Server.

A. MD5 produces a 160-bit result.
B. SHA-256 is an extension to SHA-1 with a longer output.
C. MD5 takes more CPU cycles to compute than SHA-1.
D. Changing1 bit of the input to SHA-1 changes 1 bit of the output.
E. SHA-1 is stronger than MD5 because it can be used with a key to prevent modification.
